Tertullian

Moreover, if we believe that some inflictions are sent on us by the Lord, to whom should we more exhibit patience than to the Lord? Nay, He teaches us to give thanks and rejoice, over and above, at being thought worthy of divine chastisement. "Whom I love," saith He, "I chasten." O blessed servant, on whose amendment the Lord is intent! with whom He deigns to be wroth!whom He does not deceive by dissembling His reproofs!On every side, therefore, we are bound to the duty of exercising patience, from whatever quarter, either by our own errors or else by the snares of the Evil One, we incur the Lord's reproofs.
